Reading the Trees Around You
Like Duolingo, but for Reading the Trees Around You. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Close-Up Clues on the Twig and The Whole Tree and Its World. It starts from scratch.

Key ideas in Reading the Trees Around You
- Needle-bearing conifers are almost always evergreen
- A few exceptions like larches turn bright yellow and drop all their needles in autumn
- A true leaf has a growth bud at the base where its stalk meets the woody branch
- Individual leaflets along a compound leaf stalk do not have buds at their base
- Oaks feature deeply cut, wavy lobes along the blade
- Maples show distinct hand-shaped lobes spreading out from the base
- Many simple broadleaves like birch have sharply serrated, saw-toothed edges
- The vast majority of broadleaf trees have alternate leaf arrangements, staggering along the twig
- Only a select few common trees (like maples and ashes) have leaves arranged in opposite pairs
- Oaks grow in an alternating pattern and never display opposite pairs
- Sassafras leaves release a strong, sweet citrus or root-beer aroma when crushed
- Pine needles give off a sharp, recognizable turpentine resin scent
- Common oaks have relatively neutral, dry scents that offer little scent-based identification
- Bark roughens and cracks as a tree expands, but distinctive textural motifs remain consistent
- Birch displays horizontal peeling curls, ash forms clean geometric diamond fissures, and shagbark hickory sheds dramatic vertical plates
- Lenticels appear as distinct raised horizontal dashes or slits that allow living inner bark cells to breathe gas through tight outer skin
